Senecio herreanus, also called String Of Watermelons, is a trailing succulent native to the semi-arid regions of Namibia and southern Africa. It sprawls across rocky hillsides in its natural habitat, cascading over ledges and storing water in its plump, patterned leaves to survive extended dry spells.
The leaves are bead-like ovals striped with translucent lines that resemble tiny watermelon rinds, giving the plant its common name. The vines trail for several feet, making it a cascading succulent well-suited to hanging baskets and high shelves. Leaf color shifts from green to softer tones depending on light intensity and seasonal changes. 
Small brush-like flowers appear in white to pale yellow during spring or summer, often triggered by a slight drop in nighttime temperatures. The blooms carry a faint, lightly sweet fragrance. 
Move it outside to a sheltered spot in summer, but protect it from heavy rainfall since excess moisture leads to rot. Rotate the pot regularly so all sides receive even light exposure. Keep it away from direct blowing air from AC vents and heaters, though it handles dry heated indoor air without issue.

Senecio herreanus does best in a fast-draining succulent or cactus mix blended with perlite to prevent root rot.
